采用水热微乳液法成功合成了单分散、粒径分布窄的化学计量比的单晶羟基磷灰石（HAp）纳米棒，并采用XRD、FETEM、FTIR和ICP-AES等手段对粉体进行了表征。采用水热法制备了直径为25-40 nm、长度为55-350 nm的HAp单晶纳米棒。HAp纳米棒的尺寸分布和形状的均匀性可能归因于w/o纳米反应器和表面活性剂的软模板，并且产物的高度结晶归因于水热处理。并对纳米棒的烧结性能和HAp生物陶瓷的力学性能进行了初步研究。结果表明，制备的HAp生物陶瓷具有较高的力学性能。(c)2006 Elsevier B. V.保留所有权利。
The stoichiometric single crystal hydroxyapatite (HAp) nanorods with mono-dispersion and narrow-size distribution in diameter were successfully synthesized via a hydrothermal microemulsion method, and the as-synthesized powders were characterized by XRD, FETEM, FTIR and ICP-AES. In the present work, a novel technique of w/o microemulsions of CTAB/n-pentanol/n-hexane/water under hydrothermal condition to synthesize single crystal HAp nanorods with diameter 25-40 nm and length 55-350 nm, was described. The homogeneity in size distribution and shape of the HAp nanorods was probably attributed to the w/o nano-reactors and the soft template of the surfactants, and the high crystallization of the products was attributed to the hydrothermal treatment. The sintering ability of the nanorods and the mechanical properties of the fabricated HAp bioceramics were also preliminarily investigated. The results showed that the fabricated HAp bioceramics possessed high mechanical properties. (c) 2006 Elsevier B.V. All rights reserved.
